Finally I have found the problem The vacuum canister at the back of the plenum has a load of hoses coming off it.The bottom 2 go into the plenum cast.Those had been left open when the hoses had been removed.They've been like it since I bought the car back and I hadn't noticed when I removed the plenum before.I removed it today to swap the iac over and noticed them open.So I removed the canister and checked all the hoses and then blew through it and noticed it was also blowing through those.So I put it all back on and have looped the pipes that come out of the plenum cast and hey presto the car idles and drives perfect now No wonder I couldn't make good boost with a vacuum leak as big as that.Good job I'm no boost monster Car goes in for paint in 2 weeks I will have a running and looking great car when I get it back
